Hund's Rules for the N=0 Landau Levels of Trilayer Graphene
Fan Zhang, Dagim Tilahun, Allan H. MacDonald
The N=0 Landau levels of ABC and ABA trilayer graphene both have approximate 12-fold degeneracies that are lifted by interactions to produce strong quantum Hall effects (QHE) at al…
Quantum Hall Superfluids in Topological Insulator Thin Films
Dagim Tilahun, Byounghak Lee, E. M. Hankiewicz +1
Three-dimensional topological insulators have protected Dirac-cone surface states. In this paper we propose magnetic field induced topological insulator thin film ordered states in…
A Quantum Theory of Cold Bosonic Atoms in Optical Lattices
Dagim Tilahun, R. A. Duine, A. H. MacDonald
Ultracold atoms in optical lattices undergo a quantum phase transition from a superfluid to a Mott insulator as the lattice potential depth is increased. We describe an approximate…
Junctions of Spin-Incoherent Luttinger Liquids with Ferromagnets and Superconductors
Dagim Tilahun, Gregory A. Fiete
We discuss the properties of a strongly interacting spin-charge separated one dimensional system coupled to ferromagnets and/or superconductors. Our results are valid for arbitrary…
Tunneling Density of States, Pair Correlation, and Josephson Current in Spin-Incoherent Luttinger Liquid-Superconductor Hybrid Systems
Dagim Tilahun, Gregory A. Fiete
We study a hybrid system consisting of a spin-incoherent Luttinger liquid adjoined at one or both ends to a superconductor. We find the tunneling density of states diverges at low…
